Abstract: A lifting reel with a four-line wire structure includes a fixed body fixed to a ceiling of a structure, first and second drums installed to the body at a predetermined interval and rotated by a driving motor, wires respectively connected to the first and second drums, and first, second, third and fourth guide rollers arranged on a top of a lifting body at regular intervals and suspended on the wires to form a four-line wire. A wire-twisting prevention device is installed between an end of the wire connected to the first drum and an end of the wire connected to the second drum so as to connect both wires with each other. The wire-twisting prevention device includes bearings installed to the ends of the wires to be rotatable, respectively. The bearings prevent the wires from being twisted while the wires are wound around or unwound from the drums.

Abstract: A multi doorlock includes a doorlock unit (200) installed to a hinged door (100), a non-powered DC motor (300) installed to the doorlock unit, and links (400) (410) having one ends connected to the DC motor and the other ends installed to a doorframe, the links being folded or unfolded with each other when the hinged door is closed or opened. The doorlock unit (200) frequently changes a braking resistance of the DC motor (300) while the hinged door (100) is opened or closed, thereby controlling an opening/closing speed of the hinged door. A relay switch (700) is connected to both ends of a power line (330) of the DC motor (300) to short the DC motor on occasions. When it is intended to fix the hinged door (100), the relay switch (700) is operated to short the DC motor (300) such that the hinged door is not moved.

Abstract: A virtual local area network (LAN) control system for controlling at least one virtual LAN through a network accessed by a plurality of terminals includes a terminal, a virtual LAN switch, and a virtual LAN controller. The terminal has a proper identifier address to access the network, or receives a proper identifier address through an external device connected to the virtual LAN switch. The virtual LAN switch sets and provides at least one virtual LAN through the network. When the terminal accesses the virtual LAN controller to request to change the configuration of the virtual LAN, the virtual LAN controller assigns authority to change the virtual LAN to the terminal so as to change from the virtual LAN to which the terminal belongs to another virtual LAN.

Abstract: An LED lighting lifting system includes a lifting device installed at the ceiling of a building to move a lifting body upwards or downwards by using a wire; and an LED lighting connected to a lower end of the lifting body and moving downwards to the ground or upwards to the ceiling together with the lifting body. A cooling device is installed between the lifting body and the LED lighting to prevent the LED lighting from being broken due to a high temperature generated when a current over a rated current flows at the LED lighting.

Abstract: An open access node receives a dynamic IP address corresponding to a terminal that requests a connection from a specific server, and provides the dynamic IP address to the terminal. Next, the open access node receives a service that is requested by a user from the terminal that is connected using the dynamic IP address, and stores a MAC address of the terminal and a service in a database. When the terminal again requests a connection, the open access node identifies a service that is requested by a user of the terminal based on the MAC address of the terminal.
